	abstract = {The aim of the present work was the recovery of nickel and copper from metal finishing hydroxide sludge by\&nbsp;kinetic acid\&nbsp;leaching. The study was divided into two main parts: First,\&nbsp;a kinetic model of precipitate leaching\&nbsp;with the presence of acid was\&nbsp;developed and\&nbsp;subjected to theoretical approach so as to determine optimal leaching conditions (pH and time). Next, the study was conducted experimentally on pure metals hydroxides and then on electroplating sludges.\&nbsp;The leaching operation was performed at atmospheric pressure with constant stirring.\&nbsp;\&nbsp;pH and solubility versus time at\&nbsp;different temperature\&nbsp;values and\&nbsp;different\&nbsp;amounts of sludge were\&nbsp;carried out. The resulting filtrate was found to contain more than 99\% of nickel and copper.},
